Azusa Tsujimori is a Japanese voice actress and singer from Chiba Prefecture. She is affiliated with the agency HIGH PINE and is known for her energetic and sincere performance style. Her nickname among fans is Azu.

Tsujimori entered the voice acting industry in 2023 when she joined the agency PUGNUS, which was then a subsidiary of EARLY WING. Only two weeks after her debut, she successfully passed an audition to become a new member of the voice actress unit SMILE PRINCESS. She was officially announced as a member on July 30, 2023, during a special stage event at the Wonder Festival held at Makuhari Messe. Later that year, she was also announced as the second voice actress for the character Aika Mizusawa from the series related to the unit, although she did not have the opportunity to perform the role in an anime adaptation. Within the group, she co-hosted the YouTube live streaming program SMILE PRINCESS Revival Live alongside her colleague Satomi Hongo.

In March 2024, Tsujimori left PUGNUS to work as a freelancer. She returned to the agency in July of the same year after it was renamed HIGH PINE. Her first role in a television anime series came in July 2024 when she voiced Hikari Tanabe in A Nobody's Way Up to an Exploration Hero.

As a member of SMILE PRINCESS, Tsujimori contributed to several musical releases. Her discography includes songs such as fakey merry game, Revolution No.1, MOVE ON BABY, and PRINCESS PRIDE. Beyond anime and music, she has also expanded her performance portfolio to include stage readings and theatrical productions, with appearances in works such as Shiroki wa Chinmoku no Machi de and Musubu Te, Kesera to Sakimidare.

The SMILE PRINCESS unit disbanded in August 2024, after which Tsujimori has continued her career as a solo voice actress and musical artist.
